This program is designed for mid-career conservators.  Participants may be selected based on order of receipt of registration, training, experience, balance of institutional and private practice conservators, number of registrants from a single organization, and geography.  Preference will be given to AIC Professional Associate and Fellow members.  Early registration is advised.

Workshop Description
A variety of different bleaching methods can be used to treat discolored and stained paper. There are cases where bleaching may be the only way to achieve an acceptable degree of legibility or visibility of an artifact, or to restore an artist’s vision of a work on paper without the distraction of disfiguring stains and discoloration.

In this workshop conservators will learn a variety of historical and contemporary bleaching methods and their appropriate uses: light bleaching, hydrogen peroxide, calcium hypochlorite, sodium borohydride, and borane tert-butylamine complex. These methods will be reviewed in the context of existing and current conservation theory, ethics, and practices.  The course will focus on practical applications of different bleaching techniques and other non-bleaching options for stain reduction—both localized and overall treatments.  Participants will perform, compare, and evaluate the techniques.

This course was offered very successfully at the Centro del Bel Libro in Ascona, Switzerland in 2004 and 2006, and by FAIC in Omaha, Nebraska in 2007.

Participants are encouraged to bring sample materials to test the various techniques during the workshop sessions.
